No. They have it right you on the other hand have the formula for glucose not sugar. They aren't the same despite what many people think. You can google it for proof

That's sucrose on the top, table sugar, a disaccharide, it is composed of the said glucose & fructose. While the latter two are individual monosaccharides.
